Elmer Gates, noted psychologist and resident of this city for the past thirty years, died yesterday morning following a fourmonth illness at his home, 2705 11th street. He was sixty-four years old.

Mr. Gates, the Son of Jacob and Phoebe (Goetz) Gates, was born in 1859, near Dayton, Ohio. He was educated in the common and normal schools, but mostly by private tutors, completing his education by taking special courses at several colleges. He married Miss Phoebe Edson of this city in 1895, and had lived here since that time.

During his scientific career he evolved a practical art of brain or mind building by systematic means, which causes an increase in the structural elements of the brain cells, fibers and whole nervous system, and increases mental capacity and skill. He also made numerous other discoveries in experimental psychology out of which he evolved an art of using the mind more efficiently in the processes of discovery, invention, education and right living. Recently he accomplished an original work in electric meteorology, higher temperatures, and was credited with a number of successful electric mining inventions. He conducted laboratories for experimental research in psychology, psychurgy and in other sciences. These laboratories he worked in were at Chevy Chase Circle, and wore given up about fifteen years ago. He received recognition for his inventions with the double microscope, the attainment of the most nearly perfect vacuum and an improved loom. All his work was free from commercial gains and instituted merely for the advancement of science He was professor of psychology at the Pennsylvania School of Industrial Art, Philadelphia, and at the Philadelphia Museum.
